The Steam Engine in Use in the London Fire Brigade.

继续我们的消防设备的插图，我们本周介绍了现在在伦敦使用的蒸汽消防车的图片。如前所述，在《期刊》的专栏中所示，伦敦旅更依赖于手动发动机来扑灭火灾，而不是蒸汽机。后者只有27个旅的使用，而前者有108个。这似乎是伦敦消防当局的印象，即手动发动机（他们称之为手动引擎）可以比蒸汽机更快地使用火力，因此，它们更需要依靠。他们似乎并不熟悉有关在这个国家使用的蒸锅的改进，始终保持锅炉中的uter锅中的热量，使发动机能够在没有任何蒸汽的情况下抬起蒸汽浪费时间。当收到警报时，锅炉下面的火灾通常会自动点燃，并且在发动机正在通往火的路上时，会产生蒸汽，以便她准备在与消防栓连接之前在全压力下工作。借助我们的自行螺旋桨，将足够的蒸汽保留在锅炉中以提供动力以推动发动机，然后生成如此迅速，以至于它们可以距离马匹在比赛中吸引的那些人距离火力。使用美国制造的锅炉，可以在两到三分钟或更少的时间内用冷水制成蒸汽，而不是通常消耗的火灾。在其他专栏中印刷的一封信中，纳什维尔的首席库存中库存了一款新的Ahrens发动机的审判，在那里用冷水在两分钟内用冷水制成蒸汽。 It .eems singular, therefore, that a great city like London, with an area j i nearly 700 square miles to protect, including her suburbs, should earners can be brought into action fully as quick, and do so much re effective service. Captain Shaw, Chief of the London Brigade, in a recent interview, claimed that the buildings of London were quite as inflammable and dangerous as those of New York. The reverse of this has always been asserted heretofore, and the inflammable architecture of American cities has been held responsible for the numerous disastrous fires with which they are visited. But if the facts regarding the buildings in London bear out Captain Shaw's statement, an additional reason is furnished for surprise at the persistency with which he adheres to his Manual Engines. The cut which we present shows the construction of the London Steamers to be very different from Ameriican Steamers, and more cumbersome. It will be observed, also, that the hose is carried on the Engine. This is light unlincd linen hose mainly, though some leather hose is used. The Engine has no Tender or Hose Carriage to accompany it. We understand that Capt. Shaw is now testing some of our American hose with a view to substituting it for the linen hose in use, and also contemplates introducingTenders to the Engines. Shand & Mason of London are the most popular Engine builders in Europe, and they may be found in nearly every city where Steamers are used. There are, however, a few Engines of American make in European cities, and, wherever they have been used, they are highly approved. Specimens of the Shand & Mason Engines arc on exhibition at the Paris Exposition, where they will be compared with at least two styles of American Steamers—the Silsby and the La France. One of the latter was shipped to the Exposition last week, and, we have been informed, a Silsby is already there. Both these are of the rotary style, while the Shand & Mason is a piston. Engine. Quite a number of the latter are in use in Canada, a fine one having just been received by the Grand Trunk Railroad for use at one of their stations. Mr. Merrywcather, representing Shand was in this city some years ago when Commissioner Pcrley, then Chief Engineer, exhibited to him some of the Steamers then in use. He expressed his amazement at the celerity with which they could be brought into action, and, undoubtedly, obtained some valuable ideas for subsequent use.
